WATCH-BARREL.

SPECIFICATION forming part Of Letters Patent N0. 71 1,476, dated October 21, 1902. Application led February 14, 1902. Serial No. 94.076. (No model.)

T0 @ZZ whom it may concern:

Be it known that LVARIAN S. COREY, residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Watch-Barrels, of which the following is a full, clear, and exact description.

My invention relates particularly to watchbarrels wherein the arbor of the main wheel is adapted to rotate after and while the mainspring is being coiled.

The object of my invention is to provide a simple and eicient means for combining the spring-barrel with the jewel-setting, main- Wheel arbor, and ratchet-wheel in such manner as to enable the arbor to rotate while the mainspring is being wound, as well as during the running of the watch.

In the accompanying drawings,wherein like letters refer to like parts throughout the several figures, Figure 1 is a top view of the main wheel of a watch embodying my invention, showing one end of the main-wheel arbor and its pivot. Fig. 2 is a plan view of the inside or lower portion of the spring-barrel, showing the jewel-setting in position therein. Fig. 3 is a plan view of the ratchet-wheel of the watch, showing the relative size and position of the interior opening through which the jewel-setting fits. Fig. 4 is a plan view of the lower or inside of the main wheel, showingr the enlarged portions of the arbor, the pivot, and the hook adapted to engage the inner end of the mainspring of the watch. Fig. 5 is a plan view of the upper side of the spring-barrel, showing the hook and jewelsetting in place. Fig. 6 is a detail cross-section through the axis ofthe main-wheel arbor, taken along the lines 2 2 of the parts shown in plan view in the preceding figures, the arbor being shown in elevation. Fig. 7 shows the jewel-setting in perspective. Fig. 8 is a plan view of the jewel-setting as seen from the bottom and Fig. 9 as seen from the top.

In the accompanying drawings, A denotes the main wheel of the watch. This wheel is mounted on the arbor B, which is of sufficient length to permit of its being journaled or pivoted within the movement-plates F and G. The arbor B is journaled at its upper end K within a jewel in the movement-plate G. I prefer to attach the main wheel to its arbor B by means of threads c, adapted to engage threads b of the same pitch on the arbor. The arbor B is journaled at its lower end in a jewel-setting E. (See Fig. 7.) This setting is composed of three concentric superposed cylinders, the uppermost cylinder h being of greater diameter than the middle cylinder h2 and the lowermost cylinder h3 being of lesser diameter than either h' or h2. These cylinders are shown as made of one piece, the three being concentricand parallel. (See Fig. 7.)

The spring-barrel C may be constructed in the usual form and is provided with a hook e, adapted to engage the outer end of the mainspring. This hook e is preferably made separate from the spring-barrel and fastened to it by means of screws or rivets. The mainspring is thus connected at its outer end to the spring-barrel and at its inner end to the arbor B by the hook g. A circular opening f is made central and concentric with the circum ference of the spring-barrel, said opening being enlarged and forming arecess f on the inner surface of the spring-barrel to receive the enlarged portion or shoulder h/ of the jewel-setting The ratchet-wheel D is provided With an openingj, located centrally and concentrically within the circumference of the ratchet-wheel and adapted to receive the shoulder h2 of the jewel-setting E. The setting projects through the openings fandj. One or more holes t' fi are provided in the spring-barrel to receive the screws or pins r" t, which extend through the spring-barrel and ratchet-wheel, thereby holding firmly together in close contact the spring-barrel and ratchet-wheel. The ratchet-wheel D has a circular concentric openingj, adapted to receive the portion h2 of the jewel-settingE. I prefer to secure thespring-barrel to the ratchet-wheel by means of the threaded or plain holes i", adapted to receive screws or pins. The holes i" are located in the same relative positions to the central opening as are the holes it' in the spring-barrel. The cylinders h' h2 are adapted to hold the springbarrel and ratchet-wheel rotatively in connection with the watch-plate F. The jewelsetting is rigidly mounted on the movementplate, being secured thereto, preferably, by

ICO

means of screws n, extending through the setting, which is countersunk at o-o o to receive the heads of screws p. Correspondingly-threaded holes 'n' are provided in the watch-plate F to receive the threaded screws n.

The jewel-setting E is adapted to fit with the required freedom about the cylindrical part h', the recess f in the spring-barrel, and the part lh2 the opening j in the ratchetwheel, the smallest diameter of the setting h3 being adapted to fit into the opening m of the movement-plate F. The screws nsecure the sprin g-barrel, ratchet-wheel, and j eWel-settin g in their relative positions in the watch-plate. This arrangementof parts allows the springbarrel to rotate in connection with the ratchetwheel around the jewel-setting held in positive position, so that it cannot get out of alinelnent While the mainspring is being Wound or let down, and makes effective the journaling of the main-wheel arbor in jewels. The

i spring-barrel and ratchet-wheel are in close contact and directly attached to each other. Having thus described my invention, I claim` as an improvement in Watches- 1. The combination'of a spring-barrel centrally recessed, a ratchet-Wheel, a jewel-setti ng within-said recess extend-ed through said ratchet-wheel, said spring-barrel and ratchetwheel being connected with each other independently of said jewel-setting and adapted to rotate freely around the same, and a mainwheel arbor extending through said jewelsetting and concentrical with said springbarrel, for the purpose described.

2. The combination of a spring-barrel centrally recessed, a ratchet-wheel having a central opening, a jeWel-settingot` three concentrically-superposed cylindrical parts of suecessively smaller diameter, the largest adapt-- ed to fit freely into a'central opening in the spring-barrel, the intermediate into central openings in the spring-barrel and the ratchet- Wheel and the smallest into a circular opening in the barrel position in the movementplate, and a main Wheel arbor pivotally mounted on said jewel, said spring-barrel being adapted to move freely with reference to said arbor, for the purpose described.

3. The combination with a movement-plate, of a jewel and jewel-setting rigidly secured thereto, a main-wheel arbor journaled in said jewel, a spring-barrel surrounding said arbor, and a'ratchet-wheel between said movementplate and barrel rigidly secured to the latter,

for the purpose described.

4. The combination with a movement-plate, of a jewel and jewel-setting rigidly secured thereto, a main-wheel arbor journaled in said jewel, a spring-barrel surrounding said arbor and journaled on said jewel-setting, and a ratchet-wheel between said movement-plate `and barrel rigidly secured to the latter, for

the purpose described.

5. The combination with amovement-plate, of a jewel and jewel-settingv rigidly secured thereto, a main-Wheel arbor j ournaled in said jewel, a spring-barrel surrounding said arbor,

a ratchet-wheel between said movement-plate and barrel, and fastening devices rigidly securing the ratchet-Wheel to said barrel, for the purpose described.

6. The combination of a spring-barrel having a central opening and arecess onv its inner surface concentric with its circumference, a ratchet-wheel provided with a central opening, said wheel being surmounted by and connected to said spring-barrel, a jewel- `setting of vsuccessively smaller concentric steps, one adapted to fit into the opening of said spring-barrel, and another intothe openings in said. ratchet-wheel and to coniine rotatively the said spring-barrel and ratchetwheel upon the movement-plate, said setting being rigidly secured to said plate and amain wheel mounted on an arbor pivotally journaled in jewels in said movement-plate,.for the purpose-described.
